Melissa Calusinski has been behind bars since 2009 when, at the age of 22, she was arrested for murdering 16-month-old Benjamin Kingan at a suburban Chicago daycare center where she worked. She has long maintained her innocence. 

For three years, Dee Warner, a Michigan mother and businesswoman, was missing and presumed dead. Her family was convinced she was murdered, but they knew that without a body or physical evidence, it would be difficult to prove.
